MACHINE FOR SUPPLYING SILK FIBAER TO PAPER.

SPECIFICATION forming part of Letters Patent No. 537,753, dated April16, 1 895.

Application filed May 7, 1894.

To all whom, it may concern.-

Be it known that we, WINTHROP M. CRANE and WILLIAM S. WARREN, citizensof the United States, residing at Dalton, in the county of Berkshire andState of Massachu setts, have invented certain new and usefulImprovements in Machines for Supplying Silk Fiber to Paper, of which thefollowing is a description, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

The present invention relates to an im provement in devices for applyingextraneous matter to paper and the like during the process ofmanufacture.

The particular object of this invention is to provide an apparatus whichshall supply uniformly and in given quantities to the paper while in theprocess of manufacture and before being compressed, silk fiber or likema terial such as appears in the paper upon which are printed banknotes, checks, paper money and the like.

Prior to this invention means have been devised for performing theoperation above referred to, but the result has not been so satisfactoryas in the present instance, it being difficult to lay the fiber at thedesired intervals and in uniform quantities. It has also been proposedto supply coloring matter or other substances to paper while in themachine by arranging a vat above the same with a series of spouts ortubes projecting therefrom over the surface of thepaper, the spouts ortubes being controlled by suitable cocks. It will be readily seen,however, that the quantity of material supplied to the paper ,will notbe uniform or at regular intervals.

lVhile the present machine has been designed especially for thesupplying of silk fiber to paper used by the United States Government inthe manufacture of currency, it will be understood that it can be usedfor any other purpose to which it is adapted such, for example, assupplying coloring matter, (he.

The invention, therefore, consists in the matters hereinafter describedand referred to in the appended claims.

In the accompanying drawings which illustrate the invention Figure 1 isa plan view showing the apparatus arranged above the Serial No. 510,355-(No model.)

apron which carries the paper. Fig. 2 is a side view partly in section,of one of the supplying wlieels. Fig. 3 is a section on line 3-3 of Fig.2; and Fig. 4 is a plan view of one of the troughs, removed. Fig. 5 is aperspective View of a paper making machine for which my invention isapplied; and Fig. 6 is a perspective view of a portion of the machineshowing in detail how the invention is applied,

certain of the material carriers being removed from the shaft.

In the drawings we have shown in Figs.5 and 6 so much of a paper makingmachine as is necessary to an understanding of the invention. Thismachine is of a well-known characterand need not be herein particularlydescribed or referred to'by letters on the drawings.

A represents so much of an apron for carrying the paper as is sufficientfor a proper understanding of the invention.

B represents a vat or other receptacle within which is placed the silkfiber or other material to be fed to the paper, this fiber beingpreferably mixed with a suitable amount of pulp to enable it to flowonto the paper. Passing longitudinally through this vat and havingbearings at each end thereof is a shaft 0 having on one end a beltpulley a by means of which connection is made with a source of power. Onthis shaft are arranged a series of revolving receptacles or wheels Dherein shown as sixteen in number which revolve in the vat and duringone portion of their revo shown in Figs. 2 and 3 and is provided with a0 suitable hub c rigidly secured to the shaft 0 by the set screw d. ThereceptacleD is hollowed out as shown at e for the reception of thelaterally extending portion f of the trough E which has a downwardlyprojecting part 9 9 5 through which the shaft passes and is free torotate. The revolving receptacle D is preferably cast in one piece andis provided with a series of independent chambers h forming in efiectbuckets, said chambers being en- 10c larged at their extremitiesadjacent to the periphery of the wheel D and having a graduallynarrowing and curved channel 2' leading from the enlarged portion towardthe center of the wheel.

Suitable openings on either side of the enlarged portion of the chamberh permit the material in the vat to enter those chambers which happen tobe immersed by reason of the rotation of the wheel D, and in thecontinued rotation thereof when the chambers are inverted, the materialtherein will flow down the channel 1 and be delivered into the trough Ewhence itis deposited upon the surface of the apron or Fourdrinier wireduring the process of forming paper and is compressed with the pulpforming a part of the body of the paper.

By having the extending portion f of the trough to fit within thecentral portion of thereceptaele D it will be seen that the material isfed directly into the trough and furthermore the front or rear sides ofsaid extension are curved as shown at Z and m so that as the partf fitsclosely within the recess in the Wheel D, said inclined parts act ascut-offs for the mouths of the channels when they are moving toward andaway from their inverted position.

While the present apparatus has been found in practice very effectiveinaccomplishing the results aimed at it must be understood that theinvention is not limited as to its main features to any of the detailsof construction shown and described, such for instance as the number andform of the receptacles or of the chambers within the same, nor to theform of trough.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is

1. In an apparatus for supplying extraneous matter to paper during itsprocess of manufacture a material carrier rotatably mounted having aplurality of chambers for catching and raising the material and asuitable receptacle for receiving the material from the material carrierarranged with one end beneath the delivery openings of the chambers ofthe material carrier, said receiving end of the receptacle being curvedto conform to the internal periphery of the material carrier andarranged to act as a cut-off for the material; substantially asdescribed.

2. In the herein described apparatus a r0- tatabl y mounted materialcarrier, said carrier being provided with a plurality of chambersenlarged adjacent to the periphery of the carrier and having an openchannel leading to the center of the carrier, said carrier beingprovided with transverse perforation to admit of the passage of thematerial into the chambers, and means for delivering the material fromthe open ends of the channel to the point at which it is to bedeposited; substantially as described.

3. In the herein described apparatus a 1'0- tatable material carrierhaving a plurality of chamberswith openings forthe passage of thematerial into said chambers, and a suitable trough arranged in a planeparallel with the plane of rotation of the material carrier, and havinga transverse projecting portion projecting into a recess formed in thematerial carrier whereby the discharge openings of the chambers comedirectly over the transverse portion of the trough; substantially asdescribed.

4. The herein described material carrier comprising a rotatable wheel, asuitable shaft supporting the same, a trough supported on said'shaft andfitting at one end in a recess formed in said wheel, and a series ofcurved chambers formed in said wheel opening near one end for thereception of the material and having their inner openings at the innerperiphery of the wheel and arranged when in depressed position toreceive material and when in an inverted position to discharge the sameinto the trough; substantially as described.

5. In combination with the vat the main shaft supported at either endthereof, and a series of revolving receptacles fixed on said shaft, anda trough arranged to receive the material from each revolving receptacleand hav ing a downwardly projecting part g through which the shaftpasses and is free to rotate, said trough fitting a recess in saidmaterial carrying receptacle; substantially as described.

In testimony whereof we a'ffix our signatures in presence of twowitnesses.
